50 cm³ of 2.5 Moldovan-3 hydrochloric acid was placed in a polystyrene beaker of negative will heat capacity its temperature was recorded and then 50 cm³ of 2.50 Moldm-3 NaOH at the same temperature was quickly added with string the temperature rose by 17°C the resulting solution may be considered to have specific heat capacity of 4.2 what is an approximate value of the murder enthalpy of neutralisation of hydrochloric acid and sodium hydroxide from this experiment

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.
